Description

Technical Field

[0001] The utility model relates to the technical field of lubrication system components, in particular to a distribution block capable of oil injection and lubrication. Background Art

[0002] Lubrication systems are often designed into various industrial equipment and machinery. They distribute lubricating oil to multiple lubrication points on the moving parts of the mechanical equipment through distribution blocks, thereby lubricating the mechanical equipment and reducing friction losses between components.

[0003] However, since the lubrication system consumes lubricating oil during operation and needs to be replenished regularly, most of the existing oil-lubricated distribution blocks on the market lack separate pipes for replenishing lubricating oil to the interior of the distribution blocks, thereby reducing the efficiency of staff in replenishing lubricating oil to the lubrication system. In addition, since the distribution blocks need to be disassembled for cleaning and maintenance and reinstalled after cleaning and maintenance are completed, most of the existing oil-lubricated distribution blocks on the market are difficult to disassemble and assemble, thereby increasing the complexity of the disassembly and assembly work of staff during cleaning and maintenance.

[0004] Therefore, those skilled in the art provide a distributing block capable of oil injection and lubrication to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the present utility model is to solve the shortcomings of the prior art and to propose a distribution block that can be lubricated with oil. By inserting the injection tube in the injection mechanism into the fixed tube and connecting the clamping rod with the injection tube, it is convenient to add lubricating oil. By sliding the slider and the slide groove in the disassembly and assembly mechanism and connecting the clamping block with the fixed block, it is convenient to disassemble and assemble the distribution block body.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] The third return spring is fixedly connected to a clamping block on one side close to the center of the mounting seat, the inner wall of the front end of the movable groove is fixedly connected to the fourth return spring, the rear end of the fourth return spring is fixedly connected to a connecting rod, the rear end of the connecting rod is fixedly connected to the movable block, the side of the movable block away from the center of the mounting seat is slidably connected to the clamping block, and the front end of the connecting rod passes through the movable groove to the outside of the mounting seat and is fixedly connected to a pull tab;

[0009] Through the above technical solution, the injection tube in the injection mechanism is threadedly connected to the external oil filling tube, and the injection tube is inserted into the fixed tube using the fixed tube threadedly connected to the distribution block body. The hinged clamping rod on the limit block is clamped and connected to the injection tube, which makes it convenient for the staff to plug and unplug the injection tube.

[0014] Furthermore, the lower portion of each of the clamping blocks slides inside the movable groove, and each of the movable blocks slides inside the movable groove;

[0015] Through the above technical solution, by pulling the pull tab and using the connecting rod to drive the moving block to slide inside the moving groove, the clamping block is forced to move along the moving groove, thereby changing the clamping relationship between the clamping block and the fixed block.

[0021] Through the above technical solution, by fixing a sealing ring to the upper end of the fixed tube and making the upper end of the sealing ring tightly fit with the injection tube, the sealing performance is improved when the injection tube is inserted into the fixed tube, preventing the lubricating oil from flowing out of the fixed tube during the process of injecting the lubricating oil from the injection tube into the fixed tube.

[0022] Furthermore, the lower end of the outer wall of the injection pipe is slidably connected to the fixed pipe, and the clamping rod is clamped and connected to the injection pipe;

[0023] Through the above technical solution, by allowing the injection pipe to be slidably connected to the inner wall of the fixed pipe, it is convenient for the staff to insert the injection pipe into the fixed pipe, and the injection pipe is clamped on the connecting block by using the clamping rod, so that the injection pipe is not easily detached from the fixed pipe, which facilitates the injection of lubricating oil.

[0036] The third return spring 605 is fixedly connected to a block 606 on one side close to the center of the mounting seat 601, and the inner wall of the front end of the movable groove 604 is fixedly connected to the fourth return spring 607. The rear end of the fourth return spring 607 is fixedly connected to the connecting rod 608, and the rear end of the connecting rod 608 is fixedly connected to the movable block 609. The movable block 609 is slidably connected to the block 606 on one side away from the center of the mounting seat 601, and the front end of the connecting rod 608 passes through the movable groove 604 to the outside of the mounting seat 601 and is fixedly connected to the pull tab 610.

[0037] The sliders 603 are all slidably connected to the slide grooves 602, and the upper parts of the clamping blocks 606 are all clamped and connected to the fixed blocks 5. By allowing the sliders 603 fixedly connected to the distribution block body 1 to be slidably connected to the slide grooves 602 opened on the mounting seat 601, the staff can slide the distribution block body 1 into the mounting seat 601 for guided fixation, and the fixed block 5 fixedly connected to the distribution block body 1 is clamped and connected by the clamping blocks 606, so that the distribution block body 1 can be stably fixed on the mounting seat 601. The lower parts of the clamping blocks 606 slide inside the movable grooves 604, and the movable blocks 609 slide inside the movable grooves 604. By pulling the pull tabs 610 and using the connecting rods 608 to drive the movable blocks 609 to slide inside the movable grooves 604, the clamping blocks 606 are forced to move along the movable grooves 604, thereby changing the clamping relationship between the clamping blocks 606 and the fixed blocks 5.

[0039] The middle part of the bottom surface of the fixed tube 201 is fixedly connected with a second return spring 3, and the upper end of the second return spring 3 is fixedly connected with a valve plate 4. By fixing a second return spring 3 to the lower end of the valve plate 4, when the injection tube 203 is inserted into the fixed tube 201, the valve plate 4 is pushed downward and the second return spring 3 is compressed, thereby opening the flow channel of the fixed tube 201 and allowing the lubricating oil to enter. When the injection tube 203 is pulled out, under the action of the second return spring 3, the valve plate 4 rises and closes the flow channel in the fixed tube 201 to prevent the lubricating oil from flowing out. The center of the lower end of the valve plate 4 is fixedly connected with a sliding rod 7. The outer wall of the rod body of the sliding rod 7 is slidably connected to the fixed tube 201. By making the sliding rod 7 fixedly connected to the lower end of the valve plate 4 slidably connected to the fixed tube 201, the valve plate 4 can stably move up and down inside the fixed tube 201, and the upper end of the fixed tube 201 A sealing ring 204 is fixedly connected, and the upper end of the sealing ring 204 fits tightly with the injection pipe 203. By fixing a sealing ring 204 on the upper end of the fixed pipe 201 and making the upper end of the sealing ring 204 fit tightly with the injection pipe 203, the sealing performance is improved when the injection pipe 203 is inserted into the fixed pipe 201, preventing the lubricating oil from flowing out of the fixed pipe 201 during the process of injecting the lubricating oil from the injection pipe 203 into the fixed pipe 201. The lower end of the outer wall of the injection pipe 203 is slidably connected to the fixed pipe 201, and the clamping rod 206 is clamped and connected to the injection pipe 203. By making the injection pipe 203 slidably connected to the inner wall of the fixed pipe 201, it is convenient for the staff to insert the injection pipe 203 into the fixed pipe 201, and the clamping rod 206 is used to clamp the injection pipe 203 on the connecting block 202, so that the injection pipe 203 is not easily detached from the fixed pipe 201, which facilitates the injection of lubricating oil.

[0040] Working principle: When using the oil-lubricated distribution block, the staff first uses the four holes on the mounting seat 601 to fix it to the mechanical equipment with bolts. Then the staff pulls the pull tab 610 and uses the connecting rod 608 to drive the moving block 609 to move, forcing the clamping block 606 to move. At the same time, the staff uses the slider 603 to slide the distribution block body 1 onto the mounting seat 601, releases the pull tab 610, and under the action of the fourth return spring 607 and the third return spring 605, the moving block 609 and the clamping block 606 return to their original positions. The clamping block 606 clamps the fixed block 5, completing the installation of the distribution block body 1. After that, the pipe for replenishing lubricating oil is threadedly connected to the injection pipe 203. Secondly, the staff installs the connecting pipe for delivering lubricating oil to the distribution block body 1. One pipe is connected to The delivery pump in the lubrication system is connected to the distribution port on the distribution block body 1. Under the action of the delivery pump, the lubricating oil is delivered to the lubrication points on the mechanical equipment by the distribution block body 1 using the connecting pipe. After that, the staff can pinch the rear ends of the two clamping rods 206 and open the clamping rod 206. Then the staff inserts the injection pipe 203 into the fixed pipe 201 and presses down the valve plate 4, loosens the clamping rod 206, and under the action of the first return spring 207, the clamping rod 206 clamps and fixes the injection pipe 203. Then the staff injects lubricating oil into the pipe for replenishing lubricating oil to replenish the lubricating oil system. Finally, the staff pinches the clamping rod 206 and pulls out the injection pipe 203. At this time, under the action of the second return spring 3, the valve plate 4 rises to close the fixed pipe 201, completing the replenishment of lubricating oil.
